[alt text: a screenshot of a tweet by @delaney_nolan, which says, "Biden/Harris saw this polling and decided to keep unconditionally arming Israel". Below the tweet is a screenshot from an article, which states: "In Pennsylvania, 34% of respondents said they would be more likely to vote for the Democratic nominee if the nominee vowed to withold weapons to Israel, compared to 7% who said they would be less likely. The rest said it would make no difference. In Arizona, 35% said they'd be more likely, while 5% would be less likely. And in Georgia, 39% said they'd be more likely, also compared to 5% who would be less likely."]
Good question - I did some digging. It seems the poll was commissioned by IMEU and conducted by YouGov, who has historically been a high-quality pollster. The poll seems to have taken place in late August. IMEU has this article on their site about it. I am not seeing any article on YouGov's site, but frankly their site is a bit difficult to navigate.
Thanks for doing some homework on behalf of lil ole me!
